FERDINAND E. ACANDA, AOF NEW YORK, N. Y.

CAR-DOOR PACKING.

SPECIFICATION forming part of Letters Patent No. 513,302, dated January 23, 1894.

Application le'd March 29,1893. Serial No. 468,193- (NO mvdelh I To all whom t may concern:

Be it known that I, FERDINAND E. CANDA, of the city, county, and State of New York, have invented certain new and useful Improvements in Doors for Refrigerator-Cars,

of which the following is a full, clear, and eX- act description.

The object of the invention is to provide a new, improved and durable packing for her- Io metically sealing the doors of refrigerator cars.

, The invention consists in a novel arrangement of packing tubes and bearing edges in conjunction with the door frame and door, as

hereinafter will be described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters ot reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of part of the car body provided with the improvement. Fig. 2 is a like View of the door adapted to be seated on the said car body. Fig. 3 is a like view showing the door seated on the car body. Fig. 4 is a face view of the packing frame; and Fig. 5 is a side elevation of the car body provided with the improvement.

As illustrated in the drawings, Figures 1, 2 3o and 3, that part cf the car body A is represented Which forms the seat for the door B, the said car body being providedl in the corners of the seat with recesses (l, extending throughout the length of each corner and 3 5 adapted to receive a tube D, made of flexible material, such as rubber. The recess C is so arranged in the corner that more than onehalf of the circular portion is in the corner, as is plainly illustrated in Fig. 1, whereby 4o the outer opening of the recess is less than the interior diameter and part of the tube extends outward through the opening to be engaged by the projecting corner E of the door B, thus causing the said corner E to be` embedded in the exible material when the door B is seated on the car body, as illustrated in Fig. 3, it being understood that part of the tube bends inward sufficiently to permit the entrance of the corner E, as shown.

In a like manner the door B having the usual 5o offset B is provided in each corner with a recess C containing a tube D', part of which projects outward to be engaged by the corner E formed on the car body A, whereby a like joint is made between the corner E and the flexible tube D similar to that of the corner E and the tube D at the time the door B is seated on the car body.

Itis understood that the tubes D and D extend around the entire seats in the car body and door, and I prefer to construct the several tubes for one joint in the shape of a frame F, as illustrated in Fig. 4, said frame being provided at one or its sides with an inlet nipple opening F', adapted to be connected with an air pump of other suitable device for inflating the said frame. The inlet F is adapted to be closed after the inflation has taken place, by a suitable cap G which will likewise be embedded in either the car body or the door B, as the case may be. It will be seen by reference to Fig. 3, that a suicient portion of either corner E or E is moved in contact with the projecting parts of the tubes D and D', to prevent air or moisture from leaking past this joint, thus hermetically sealin g the door on the car body. It will be obvious that when the door is closed, the meeting corners of the door and the frame will present a narrow edge or ridge to the exposed surface of the respective packing tubes, so that only aslight power will be required to force the door onto its seat and compress the packing tubes. It will further be seen that no special means are necessary to hold the tubes D and Din their respective recesses C or C', as the greater portion of the tube is embedded in the circular recess or rabbet, thus preventing accidental displacement of the tube whenever the car door B is removed from the door opening.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The arrangement of the elastic packing tubes within recesses made in the corners of the door frame and door respectively, in combination with meetingcorners of the door frame and door, which are adapted to press required to close the door is diminished, as pon the paelllzing tubes, as herein shown and `set forth.

escribed, w ereby when the door closes the 1 said meeting corners will present a narrow FERDINAND E' CANDA S'edge or ridge against the exposed surface of Witnesses:

the packing tubes, and thus produce an efi EDGAR TATE, fective seal While at the'same time the power E. M. CLARK.
